TYEE WRITIILJG MACHINE.-

To all whom it may concern Be it known that I, 1)}HL1PPE on GLAIIECY, acitizen of the United States, and a resident of Boston, county ofSutlol'k, and State of lilassachusetts, have invented certain new anduseful. lmproven'icnts in lype-llritingr hlachines, of which thefollowing is a full, clear, and exact description.

This invention relates more particularly to a foldable't'ront strike orother visible typewritingmachine.

One of the, principal objects of the in vcntion is to provide atypewritinn machine in which the platen carriage and its direct supportmay be folded rearwardly and downwardly within the main tranuor mainframe part of the machine and the keyboard folded upwardly and inwardlyalso within the main frame or main frame part thus confining);substantially the entire mechanism within the i'nain frame part oi themachine in order that the working parts may be protected as well as themachine made compact and convenient for transportation purposes.

Another object of the invention is to pro vide a type-writing machine inwhich keyoperated levers comprising two parts may be both mounted upon acommon rod or axis and so constructed as to form a knuckle or knee-jointin order that one part of each key-operated lever may told with respectto the other part without disconnecting the parts.

Other objects of the invention are to pro vide a keyboard frame partwhich is toldable upwardly with a part of the key-operated levers andmeans whereby the toldable parts of the lniy-operated levers may belocked and held to said keyboard frame part; to provide a machinewherein upwardly and rearwardly moving type-bars are employedand whichtype-bars are actuated by relatively toldable parts of key-operatedlevers; to provide simple means as an eseapenientmechanism fortypewriting machines: to provide simple operating mechanism forimparting a lengthwise step-by-stepteed to a ribbon; to provide meanswhereby ribbon spools may be ii'rictionally held; to provide a ribbonholder which may move to and from the platen; and which when the platenis Specification of Letters latent. lPg tguyg fl 5 1% 1918 Applicationfiled. fliarch 4, 1916.

given a compact movement is adapted to fold automatically to a compactposition; to provide simple means for releasing the escapement to adaptthe carriage to move freely along the carriage bed; and to providesimple and etticient line-spacing mechanism for the platen.

A further object of the invention is to provide simpleand c'llicientmechanism for shitting the platen and carriage to adapt the type-bars tohave a plurality of type or characters thereon.

A still further object of the invention is to provide means whereby theribbon feed and the cscapemcnt mechanism may be simultaneously operatedby the universal bar.

Another object of the invention is to provide a typewriter in which thetype basket and type-bars may be moved bodily from a normal operativeposition to a more com pact one.

A still further object of the invention is to provide a machine "whichis simple in construction, which may be readily made and assembled, andwhich when compact provides a substantially uniform package.

llith these and other objects in view, the invention will be hereinaftermore particularly described with reference to the accompanying drawings,which form a part of this application, and will then' be pointed out inthe claims at the end of the description.

In the drawings, Figure 1 is a front elcva. tion of one form of machineembodying the invention.

Fig. 2 is a longitudinal section, partly in elevation. of the machine.

Fig. 3 is a plan view partly broken away.

Fig. at is a fragmentary view, partly broken away and partly in section,showing a part of the means for operating the escapement and the ribbonfeed mechanism.

Fig. 5 is an enlarged fragmentary side elevation of a part 01" theescape-men's operating mechanism.

Fig. 6 is a side elevation of a partof the cscapement actuating meansshown in Fig.5.

Fig. 7 is a fragmentary enlarged view showing one kind of joint for thetwo parts of the key-operated levers to adapt both parts in one positionto operate in unison and to permit relative folding between said parts.v

Fig. 8 is an enlarged section, partly in elevation, of means for holdingthe platen carriage support in its normal operative position; and V Fig.9 is a View similar to Fig. 2, partly diagrammatic,showing aconstruction wherein the type basket and type-bars may be1n0\'fi(l,fl'0li1 a normal operative position to a compact one below theupper surface of the main frame or main frame part.

llhe main frame. or main frame part 10 has upright corner pillars orposts 11 with the usual rubber tips or feet 12 and connecting the postsat the lower portion thereof is a base 13. At the upper portion of themain frame part is a top plate or member 1st and. there may be sideplates if desired, it being understood that the frame or main framepart, may be of the usual or of any preferred construction. Ali theforward portion of the. machine is a luzyboard frame part 1.5. Thiskeyboard frame part 15 is hinged atltl to the main frame part and at theouter portion thereof may be provided with rub her feet of the usualkind. The keyboard frame part is tray-like in form and is adapted tofold upwardly and inwardly as shown in dotted lines in lfig. The hingeor pivot 16 is in the form of bolts located on opposite sides of themainframe part in alineineni, and said bolts have threaded stems whichare engaged by thumb nuts 17 which assist in holding the keyboard framepart in its folded and in its normal operative position. This luayboardframe part 15 at its inner portion is provided with an abutting surface18 which adapted to engage a substantiallyL-shaped spring 1f) secured tothe frame base 13 so as to position and hold said frame part in anormally horizontal position, and in the folded position of said framepart the latteris retained in such position by means of a spring 20, oneend of which is secured to the under surface of the frame part 13 orotherwise held as desired, the thumb nuts 17' serving as additionalholding Il'lQtlllS for said frame part.

A l-zeyboanl if is mounted to move with the keyboard frame part 15. Thiskeyboard may be of a universal or standard kind and con'iprises keys 22which are arranged in banks or groups and are mounted upon the upperends of vertical portions of levers 23. 'lhe'levers 23 are each formedin two parts 24; and The parts 2%. and 25 are in alinement when in anormal operative position and all of the parts of said levers arepivotally held to a transversely extending rod 26. The rod 26 is held ina main frame part of the machine between the forward corner posts 11. ofthe main frame part or in any other desired way. The parts 25 of thekeyoperated levers extend horizontally and are in alinement with thehorizontal port-ions of the parts 24:, and on one of said parts, as thepart 24: of each lever, is a shoulder 27 which is adapted to engage ashoulder 28 of the part 25 when in normal operative position as shown inFig. 2, so that on the depression of one of the keys the inner end ofthe-part 25.0f the two-part lever on which the key is mounted will beforced upwardly. Each lever 23 is restored from a depressed position toits normal operative position by a spring 29, one end of which issecured to the base 13 and the other end passed through an aperture inthe key lever part The shoulders 27 and 28 and the mountings of theparts 2% and provide a knee or knuckle joint which adapts all of theparts of all of the key-operated levers to fold relatively to the partsas shown in dotted lines in Fig. 2.

The inner ends of the parts 25 of the keyoperated levers 23 have a pin30 and each pin is adapted to move in a slot 31 of an arm 32. The armforms a part of the bellcrank lever and each bell-crank lever ispivotally held in a bracket 3: extending upwardly from the base 13 or toa common pivot rod as preferrtal. The arm of each bell-crank lever ispivotally held by a knee or other joint at its outer end 36 to anupwardly extending link 3'7, and said link a 37 at its upper end ispivoted at 39 to the short arm 40 of a. type-bar 41. Each typebar it isadapted to have a plurality of type or characters thereon according towhether a single case shift. or double. case shift is employed. Thetype-bars are adapted to rest at their forward ends upon a felt, rubberor other cushion 42 and are arranged in a curved path within the typebasket 41:3, said type basket being suitably held in the main fran'iepart of the machine in such a way that when a key-operated lever ismoved on the depression of a key, the actuation of its cooperatingbell-crank lever will force a link 37 downwardly and this will cause.one of the type-bars to move the type upwardly and rearwardly to make animpression upon the work sheet about the platen etat'in the usual way.

As a means to lock-the keys and the foldable parts of-the key-operatedlovers to fold and unfold together, a bar &5 extends transversely of themachine over the parts 24. and under the parts 2% is a substantiallyU-shaped rod 46. The rod L6 is pivotally mounted. between the sides ofthe shallow frame part 15 and is adapted to be forced the transverselyextending bar to and the portion l7 and thereby prevent theirdisarrangement. The bar 45 may have a rubber or other strip forming anengaging surface for the key-operated levers, and the rod 4:6 may have aknob or handle to move the same, it being understood that the key-leverparts 24 are not held so tight between the bars 46 and l? as willprevent such relative movement of the keyboard frame part and thekey-lever parts as as is necessary because of their difierent pivotpoints.

The platen l-l is mounted upon a platen carriage 48. This platencarriage s8 is adapted to travel transversely of the ma chine on afoldable support d9. This support .49 has two members 50 and 51 whichare hinged together at 52 at the upper poi;-

' tion of the machine. The support member 51 rests when in a normaloperative position upon a transversely extending bar 53 forming a partof the vertically movable member 50 of the platen carriage support. Theplaten carriage may be variously constructed, As shown it comprises endpieces or brackets 5d which extend upwardly from p a carriage base 55and said base may be held to' travel. transversely of a carriage bed.The carriage bed may extend rearward as far as the hinge 51 or'may besupported between foldable arms or in any other desired Way. Thecarriage end piecesb l support the axis or shaft 56 of the platen andsaid end pieces may also support a paper apron 57 in which may bemounted a pressure or teed-roll 58,

there being paper fingers and such other parts as are usually employedto hold and guide the work about the platen.

While the platen carriage with its bod forming one member of thecarriage support is adapted to fold rearwardly and down wardly so as toextend within the main frame part 11 and between the sides thereof whenin a compact position. as shown in dotted lines in Fig. 2, the platencarriage and both members of the support are adapted to be shifted forupper case characters :when in a normal operative position, though itwill be understood. that the platen carriage may have two shiftmovements instead of one, or the type basket itself may be shifted as insome forms of writing ma chines, if desired. The movable carriagesupport member 50 at each end has upright portions 59 and these portions59 have a tongue and groove or other connection with the sides oi themain frame part 11 or otherwise held to move vertically thereon so thatin its vertical movement the platenv carriage with its bed 54 willpartake of such vertical movement. A pin or stud 60 projecting inwardlyfrom each side of the main frame part 11 enters a slot 61 in eachcarriage support portion 59 and adapt- 13. An arm extends upwardly fromthe shaft 63 at each side of the machine and connected to each arm 65 isa link 66. Each link it is connected to an arm 67 of a bellcrank leverwhich is mounted in. the bracket on the same rod as the bell-cranks 33are mounted. A shift lever (58 is located at each side or the machine sothat the platen carriage may be shifted from either side of thekeyboard, and each shift lever comprises two parts 59 and 70, which havea knee joint connection similar to the keyoperated levers 23 in orderthat said shift levers may have one part fold relatively to the otherpart and the toldable part thereof movable as a part of the keyboardwhen the keyboard frame part is folded to its compact position. Theparts 70 of the shift levers are adapted to operate the bell-crank arms67. These arms or either of them oper ate the links 66 and theeccentrics G2 on the depression of the shift keys, and this movement ofthe eccentrics (52 forces the carriage support men'ibers 50 and 51 toplace the printing point and the platen in position for writing uppercase characters.

The platen carriage and its support may be held in its normal operativeposition against relative backward folding movement in any desired way.As shown, a pin or stem 71, Figs. 3 and 8, has a knob or head 72 thereonand is normally forced inward by a spring 73. The pin 71 is adapted toengage an aperture 74 in one end of the carriage bed or other part andlock said bed to the vertically moving supporting member 50 so that theplaten carriage cannot fold rearuuirdly until the pin is released. Theplaten carriage may also be held against a swinging or free movementwhen in its folded compact position. by a releasable pin or part 74 orotherwise, which is held to the frame of the machine and is adapted toengage under a part of the foldable carriageor guides 7 7. The universalbar is normally forced downwardly in the path of the keylevers 23 bysprings 78. The universal bar has inwardly extending arms 79 and thesearms extend upwardly, as at 80, at opposite sides of the machine. At theupper ends of the parts 80 are heads or slides 81 and 82.

These heads 81 and SQ'are suitably guided at their upper ends bybrackets 83 or other wise, and said heads are adapted to engage rollersSat and respectively, both of which are mounted upon a transverselymovable rod 80. The rod 86 is suitably supported in the machine frameand is normally forced against the action of the heads 81 and 82 by oneor more springs 87. The heads 82 are each provided with a straightportion 88 forming a normal seat for the rolls 85 and a beveled orinclined part 88 forming a wedgedike actuating part on each had.livotally held to each head is a pawl or dog 85). The pawls 80 havetheir free ends normally torced outwardly beyond the heads to provideteeth 00. and each tooth is adapted to move inwardly within a recessedpart of the head during the upward movement of the heads and rods 80 onthe depression of the key-operated levers. A spring 01 tends normally toforce each pawl 80 out wardly or permit the pawls to be moved inwardlyduring the upward movement of the heads. The upward movement oi? theheads will cause the rolls and rod 80 to move transversely of themachine to a point indicated by the first dotted line of roll as at 01,Fig. As the pawls89 are forced above the rolls 8t and owing to theirbeing held. to yield, they will not operate said rolls but immediatelythat the teeth ol? said pawls are above said rolls the teeth or ends 00thereo't will engage the upper portion of the rolls, and during thedowi'nvard movement ol the universal bar and heads 8:2.an additional'throw will be given to said rod 80 to the point indicatcdby dotted roll01, said pawls' being each held against upward movement by means of,astop or part 02 located immediately above said pawls. Two lugs orprojections 93 which are spaced apart and project rearwardly from thetransversely movable rod 80 are adapted to span an arm 9-1 of anescapement detent or arm 95. The detent 95 is pivoted at 90 and has aretaining tooth or dog 97 and a longeutooth or dog 98 which are adaptedalternately to engage the teeth of arack 00 by reason of thereciprocatory n'lovement of the rod 80. The dog 98 is released duringthe additional throw given the rod 86 by the pawls S9 and this willplace the (log 97 in engagement with the rack, said dog 07 being"released on the return. movement of the rod 80 and the universal bar.The rod 86 may be operated aerate-i instead of partly on the upwardmovement of the heads 81 and 82 thus avoiding any lost motion-betweenthe projections 93 and arm oi the detent 95, in which case said heads donot move the rod 86 on their upward movement and the we lee portions aredispensed with. The rack 9?) is supported under the platen carriage andmay be pivoted .at one end, as at 100, to adapt the escapement rack tobe released from the escapement dogs, as will be presently described.The platen carriage is normally under tension of a spring in a drum 101mounted under the carriage supporting members .to shift therewith and isadapted through the usual strap or connection to move the carriage aletter space each time the universal bar is operated, though instead ofthe particular form of mechanism shown a limbcr and a fixed dog adaptedalternately to engage the rack teeth, as is common in many forms oftypewriting machines, may

be employed and operated by the rod 86 or- By having the in any otherdesired way. universal bar actuate the reciprocating bar 80 on itsdownward movement rather'than ils upward movement the letter feedmoveafter the type have moved against the work on the platen; otherwisethe carriage might move at or about the time an impression is made hythe type. The rod 86 may be made to reciprocate from right to leftinstead of left to right to release the escapement, in which case thedog 97 will normally engage the rack; The heads 81 and 82 will in thatcase be reversed.

It will be evident that the escapment dogs and racl; which are bothmounted upon the platen carriage support may by reason of the arm Ellresting between the projecting lugs or parts 03 on the transverselyextending rod 80 be separated therefrom when the platen carriage and itssupporting bed are moved to a compact position, and on the platenvarriag'e being restored to its normal operative position the arm 94:will automatically position itself between said lugs or projections 03ready to be operated when the keys and universal bar are operated.

The carriage may be letter spaced without printing in any suitable way.The space bar 102 is connected to level-S103. These levers 103 aredivided into two parts, 10st and 105, and said two-part lovers are mounted upon the transversely extending rod 26 and have a knee-jointconnection similar to the key-operated lovers 23, so that the space barand the forward parts 103 of the twopart levers may fold as a part ofthe keyboard. The inner parts 105 of the key operated levers simplyactuate the universal bar and have no connection whatever with any ofthe printing instrumentalities,

arass-1 The ribbon holder 106, is located substantially centrally of themachine and is adapted to support a ribbon in position to cover theprinting point on the platen 14.

The ribbon holder 100 is pivoted 107 to a part of the main frame and onopposite sides of the holder, adjacent to its pivot 107, are springs 108and 109. The spring 108 is secured to the foldable part of the carriagesupporting member 51 to fold therewitl'i while the spring 100 is held toa fixed part. The spring 108 is of greater strength than the spring 109so that when the spring 108 is in the position shown in Fig.2 the holderwill be held against downward folding movement, but when the spring 108is folded away from the holder 106 to the position shown in dotted linesin said figure the spring 109 will force the holder rearvv ardly anddownwardly on its pivot to a compact position. That is, the ribbonholder will fold over to a substantially horizontal position, carryingthe ribbon held thereby and may be restored to. its normal operativeposition manually or otherwise when the platen carriage is restored toits normal operative position. The ribbon from the holder 106 passesabout ribbon spools 110 and 111 mounted upon downwardly extending arms112. The ribbon spools may be detachably held to permit the ribbons tobe readily re placed and said ribbon spools may each be frictionallyheld to its support against too free movement by a spring 113 which maybe in the form. of a strip or as a disk as preferred. he ribbon spoolsmay have a toothed disk portion or ratchet wheel 11% as a part thereofand adapted to engage the teeth of the ratchet wheels are pawls 115. Thep'awls 115 are mounted upon inwardly extending arms 110 held to thevertical rods so that during the reciprocation oi? the universal bar andparts 80 the pawls 115 will impart a rotary step-by-step movement to theribbon spools to wind the ribbon from one spool on to another.

While the drawing shows both pawls 115 in engagement with the teeth 0?the ratchet wheels of the ribbon spools only one pawl is in engagementat a time, and these pawls may be moved to engagement or disengagementmanually and imlependcntly or they m y be moved simultaneously as iscommon in some forms of tvpewriting machines,

whereby one pawl is disengaged when the other pawl is engaged in orderthat the direction of feed of the ribbon may be reversed at will. Theribbon ti-ed thus operated simultaneously with the movement of the meansfor tri ipinn the escapement, the ribbon teed being actuated during onemove ment of the universal bar and the escapement mechanism durim thereturn move ment of said lllllYil'Sill bar. The pawls 115 F"? sill andthe direction of teeth of ratchet disks 11 1 may be reversed to permitthe spools to be rotated during the downward movement of the universalbar instead of the upward movement.

The carriage may be released to permit the same to move freely along itsbed. As one means a bell-crank lover 116 is piV0t ally held to one ofthe carriage end brackets 51. This lever 116 is pivoted at 117 and hasone arm. thereof formed as a finger portion 118. The other arm of saidlever is slotted as at 119, to engage a pin 120 on the carriage rack.This pin 120 is slidably held in the carriage end bracket and isnormallyiorced in one direction by a spring 121 arranged in said slot,said rack, as before stated, being pivoted at one end thereof and at itsend opposite the part eneagcd by the lever 116. As the lever 116 isdepressed the rack will be shifted to one side and be released from theteeth of the escapemcnt dogs thus permitting the carriage to be movedfreely in either direction along the carriage bed.

As a line-spacing means for the platen 4A a ratchet wheel 122 isprovided on the platen shaft 56 at one end thereof. The teeth of theratchet wheel are adapted to be engaged by a pawl 123. The pawl 123 ismounted upon a lever 121 which is pivotally held to the platen shaft 50and is adapted to move about said shaft independently thereof, andduring such movement will cause the pawl 123 to engage the teeth of theratchet wheel and rotate the platen 4 1. A segment 125 is held to orformed as an extension of one of the carriage end brackets 5.4, and saidsegment is slotted as at 126 and in said slot is held an adjustable stop12?, as a bolt and nut. lhis stop 127 may be variously positioned in thesegment and controls the distance the line-spacing lever 12% is adaptedto move. By adjusting the step 127 the pawl 123 may be made to move theratchet a single space or two spaces or more, according to the distancethe lever 12% adapted to be moved on its axis. The platen is thusadapted to be line spaced varying degrees.

The operation of the invention will be readily understood from theforegoing description when taken in connection with the accompanyingdrawings. The parts being in the position shown in the drawings, it willbe evident that if the keys are operated the key-levers will be alsooperated and the inner portion of the key-levers will move thebell-crank levers 33, links 37, and type-bars 41 to make an impressionon the work sheet about the plat-on n. During the movement of thekey-operated levers the universal bar will be operated and the upwardn'iovemcnt ot the universal bar with the parts 80 will aciir its theribbon feed mechanism on the upward movement thereof and on the returnmovement of the universal bar the escapement dogs will be trippedthrough the action of the heads 82 as already described. lhe platencarriage and its supporting members may be given a vertical shiftmoven'ient by means of either one of the shift keys, the carriage andits supporting means being restored to its normal position on therelease of said keys by springs or otherwise. If the machine is to bemade compact. for t ransportation, the retaining pins '71 may bereleased which will permit the foldable member of the carriage supportand the platen carriage. with the spring 108 to be folded retn'wzn'dlyand downwardly, as shown in dotted lines in Fig. 2, and the keyboardframe part. 15 with the parts 24 of the key-operated levers, the spacebar and the shift keys may be also moved to a compact position, as shownin dotted lines in said figure.

In Fig. 9 the construction of the machine is substantially identicalwith that already described, except that the type basket, typebars andpart of the type-bar action is constructed in such a way that thetype-bar basket may be moved below the upper surface of the frame, sothat no part of the typewriter mechanism will extend above said surfacewhen the machine is compact and in its transporting condition. Theconstruction is shown in Fig. separately from that of. the disclosure inFigs. 1 and 2 in order not to confuse the parts, and it is to beunderstood that this construction may be embodied with the mechanism andparts shown in Fig. 2 orwith any other suitable mechanism. As shown inthis ligure the type basket 128 is supported by uprights or standards129 which have a pin-and-slot connection as 1 -30 to adapt the typebasket to lower to the position shown in dotted lines.

The type bar basket. may be engaged when in a normal position by a latchor catch 131 which is normally pressed to an engaging position by aspring 132, and which may be readily released by the operator so as toadapt the type basket to lower. The typebar operating levers 132 aremade in two parts 133 and 134 which have an elbow or knee joint as 135,to adapt the links to as sumo the. position shown in dotted lines whenthe type basket islowcrcd. 'lhe joints between the parts 1 -13 and 134of the links are such that when in the position shown in full lines apositive connection is made between the type-bars and the bell-cranklevers 135, said levers 1 -35 being operated by the key-operated loversin the same manner as already described.

From the foregoing it will be evident that a simple and ellicicnt.typewriting machine is provided wherein the keys forming a part of auniversal keyboard and the platen carriage may be moved or folded to amore conlipact bosition when not in use than when in :li normaloperative condition; that simple and efficient means are providedwhereby the foldable part of the keyboard may be retained or lockedagainst movement during such folded movement; that means are providedwhereby the type basket may also be moved to a compact position; thatsimple and efficient. ribbon mechanism is provides; that a separal'ileescapement mechanism is provided whereby the platen carriage may foldfrom a normal operative position to an inoperative and compact one andthe connection with the escapement mechanism again effected withoutadjustn'ient of parts; that simple case shift means is provided; andthat said machine is simple in construction and may be readily made andassembled.
